Description

[Detailed Description of the Invention] The present invention relates to an easy-to-handle package in which a plate-like object such as a building board or an object to be packed, such as a stack of these objects, is packed in corrugated cardboard and a shrink film.

Traditionally, plate-like materials such as architectural decorative boards are stacked together, wrapped in shrink film to prevent moisture, and then placed in a cardboard box to form a package before being shipped. ing.

In order to make such packages easier to handle, if a small hole is provided on the end surface (i.e., the end surface of the cardboard box) for the hand, the moisture-proofing and protective properties will be reduced, and the handle for the above-mentioned handle will be reduced. If small holes were not provided, there was a problem that it would be difficult to handle.

The present invention was developed to solve these problems all at once.In a package in which a plate-shaped or rectangular parallelepiped-shaped object is surrounded by cardboard and the outer periphery is shrink-wrapped, the end of the object is A moisture-proof layer made of a moisture-proof board or a moisture-proof sheet is provided on the surface with or without a cardboard for protecting the end surface, and a shrink film with a thickness of 40μ or more is used to cover the outer periphery of the cardboard enclosure of the item to be packaged. By covering the wood so as to form an opening in the shrink film at the center of the butt end, it has excellent moisture resistance and protection.
Moreover, the present invention provides a package that can be easily handled.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Figures 1 to 4 show a package A according to the present invention. 1 is a cardboard box for protecting the top surface of the object B, and 2 is a ground protection part 2a that protects the ground (lower surface) of the object B. and a corrugated board for ground protection, 3 having end face protection parts 2b, 2b standing upright on a pair of opposing side edges of the ground protection part 2a and protecting the end face of the object B, 3. It has side protection parts 3a, 3a to protect and end face protection parts 3b, 3b to protect the end face of the object to be packed B, and the side periphery is assembled into a frame shape by fixing both ends with adhesive, stable, etc. This is cardboard for surface protection.

A moisture-proof layer 4 made of a moisture-proof plate or a moisture-proof sheet made of foamed resin or the like is provided on the inner surface of the end face protection portions 3b, 3b of the side peripheral surface protection corrugated board 3.

Further, as shown in FIG. 5, at a pair of opposite side ends of the ground protection part 2a of the ground protection cardboard 2 on the side opposite to the hollow surface protection parts 2b and 2b, the side peripheral surface protection Extending portion 2 extending approximately the same dimension as the thickness of the corrugated cardboard 3
C and 2C are provided.

The object to be packed B is surrounded by each of the cardboard boxes 1 to 3, and the corrugated cardboard surrounding body of the object to be packed B is shrink-wrapped with a cylindrical shrink film 5 to be integrated. A package A is constructed.

That is, the object to be packed B is placed on the ground protection part 2a of the ground protection corrugated board 2, and the side peripheral surface protection corrugated board 3 is placed on the outer periphery of the end surface protection parts 2b, 2b of the ground protection corrugated board 2. The extension portion 2 of the ground protection portion 2a is arranged so that the protection portions 2b and 3b are aligned to cover the side peripheral surface of the object to be packed B.
The lower end surface of the cardboard 3 for protecting the side circumferential surface is placed on C, 2C, and the cardboard 3 for protecting the side circumferential surface is placed.
By placing the top surface protection cardboard 1 on the upper end surface so as to cover the top surface of the object to be packed B, the object to be packed B is surrounded, and the end surface of the object to be packed B is placed on the ground. A moisture-proof layer 4 is provided through the end face protection parts 2b, 2b of the protective corrugated board 2.

Further, the outer periphery of the corrugated cardboard enclosure of the article to be packed B is shrink-wrapped with a cylindrical shrink film 5 having a thickness of 40 μm or more, and the central part of the end surface (the wooden surface protection part of the corrugated board 3 for side peripheral surface protection) is 3b, 3b (center part of the outer surface) are coated to form openings 5a, 5a of the shrink film 5.

Therefore, since the lower end surface of the side peripheral surface protection corrugated board 3 is placed on the extension parts 2 c and 2 c provided at the side ends of the ground protection part 2 a of the ground protection corrugated board 2 , it is shrink-wrapped. Since the integrity of the ground protection corrugated board 2 and the side peripheral surface protection corrugated board 3 is improved, the protection properties can be further improved, and the appearance of the packaging can also be improved.

Also, the opening 5a of the shrink film 5.

5a is provided on the end surface of the package A, so it is possible to lift it by placing your hands on the openings 5a, 5a.
Easy to handle.

Here, when the thickness of the shrink film 5 is less than 40 μm, moisture resistance and protection properties are reduced, and
As mentioned above, it is undesirable because it is easy to break when lifting it by hand.

Further, since the moisture-proof layer 4 is disposed on the end surface of the object to be packed B, the moisture-proof property does not deteriorate even if the openings 5a, 5a of the shrink film 5 are provided on the end surface.

In particular, when the moisture-proof layer 4 is made of foamed resin, it functions not only as a moisture-proof material but also as a cushioning material, thereby increasing protection.

FIG. 6 and FIG. 7 show a modification of the above embodiment, and FIG.
The figure shows a corrugated board 6 for top and bottom protection in which the corrugated board for top and bottom protection 1 and the corrugated board for ground protection 2 in the above embodiment are integrally formed, and the corrugated board 6 for top and bottom protection and the corrugated board 3 for side peripheral surface protection are shown in the figure. It surrounds the item B to be packed.

In addition, in FIG. 7, end surface protection parts 1'a, 1'a having a height approximately half of the end surface of the object to be packaged B are provided at a pair of opposing side ends of the top surface protection corrugated board 1'. Similarly, end surface protection portions 2' having a height approximately half of the end surface of the object to be packaged B are attached to a pair of opposing side edges of the ground protection corrugated board 2'.
b.

2'b.

The other configurations are the same as those of the above embodiment, and the same effects can be achieved.

In the above embodiment, the cardboard 3 for protecting the side circumferential surface may be arranged on the inner circumferential surface of the end surface protecting parts 2b, 2b, and
It is not necessary to provide the end surface protection parts 2b, 2b on the ground protection cardboard 2.

In these cases, the moisture barrier layer 4 is made of cardboard for protecting the end surface (
The object to be packaged B directly without going through the end surface protection parts 2b, 2b).
It will be placed on the end surface of the wood.

In particular, the end surface protection parts 2b, 2b are attached to the ground protection cardboard 2.
If not provided, the same corrugated board 1 for protecting the top surface can be used as the corrugated board 2 for protecting the ground, and the package can be formed more economically.

Furthermore, in the above embodiments, the cardboard surrounding the object to be packaged B is a combination of a plurality of cardboards, such as a cardboard for protecting the side circumferential surface and a cardboard for protecting the top and bottom. Of course, a normal box-shaped cardboard may also be used.

As explained above, according to the present invention, it is possible to improve ease of handling and ensure moisture resistance, thereby providing an easy-to-handle package with excellent moisture resistance and protection. It is.
